Download a file from git, open it, run fluent pub get, and an error occurs:
pubspec.yaml has no lower bound SDK constraint.
you should edit pubspec.yaml to contain an SDK constraint:
environment:
SDK: ‘>= 2.10.0 < 3.0.0 ‘

add to pubspec.yaml:
environment: SDK:’ >= 2.10.0 < 3.0.0 ‘
after rerunning fluent pub get, an error is still reported, indicating that the SDK constraint is not added. Later, it is found that the subfolder example of the home folder also contains a pubspec.yaml file, in which the SDK constraint is not added
after adding constraints, run fluent pub get.
